The purpose of this Notice is to add the R00 Pathway to Independence mechanism to the list of grants eligible for CAPTR administrative supplements (previously restricted to R01s, R37s, and P01s). The original K99/R00 grantee has to have transitioned to the Research Phase (R00) of the award prior to the submission date (March 23, 2009) for the CAPTR administrative supplement request. No other career development (K) awardees are eligible to apply for a CAPTR supplement.
